After her homeland, the Stellar Archipelago, is destroyed by an unknown catastrophe, Akemi is sent through an experimental portal to Oumeria, a world she has never known. Lost in the frozen lands of Dunyamane, she is taken in by Matthew and Viktor, two Human teenagers suffering from a mysterious magical illness known as the Anomaly.

Years later, Akemi and Matthew settle in Frejwind, where they meet Sana and Adam. Together, they form the Wanderstar, a team of heroes protecting the continent from magical threats. But when the King of Orolwen transforms into a monstrous Calamity during his coronation, the fragile peace between Humans and Inhumans collapses.

Still haunted by the loss of her homeland, Akemi embarks on a journey to uncover the truth behind the Anomalies, the Celestial Rituals, and her own forgotten origins.
